Introduction to Oncology
Oncology is the study of tumours; oncologists are the people who study tumours. Carcin/o is a medical term that means cancer. All cancers are considered neoplasms which means new growth. Cancerous tumours are called malignant. A non-cancerous tumour is called benign (good); this is determined through a biopsy (Bx). A benign tumour often has the suffix -oma at the end of the word. However, a malignant tumour indicates that there is a cancerous growth. Malignant cells usually multiply rapidly, forming a mass of abnormal cells that enlarges, ulcerates and sheds malignant cells that invade surrounding tissues. These terms will usually have the word carcinoma at the end of the word. The medical specialty of oncology primarily treats patients who have cancer.
The suffix -oma means tumour, an abnormal tissue mass that forms through uncontrolled cell growth and divides more than it should. The cells also do not die when they should.

What is producing cancer? What are some carcinogens? A carcinogen is a cancer-generating/producing substance. Carcin/o means cancer, and the suffix -gen means producing. There are various causes of cancer, yet many are unknown at this time. Bacteria and viruses, diet, hormones, smoking, radiation, alcohol, environment, chemical, and genetics are all potential risk factors and causes of cancers.
